Railway Track Degradation Modelling Using Finite Element Analysis: A Case Study in South Africa
Ntombela Lunga, Masengo Ilunga
This study utilizes finite element analysis (FEA) to examine railway track degradation, emphasizing the performance and durability of rail components under varying loading conditions. Static, dynamic, and fatigue simulations are conducted to identify high-stress regions, particularly at rail joints and sleeper interfaces, which are most prone to accelerated wear and failure. A refined three-dimensional (3D) modelling approach enhances simulation accuracy, providing detailed insights into stress distribution and contact dynamics. NX Nastran is used for static and dynamic load analyses, while SolidWorks is used for fatigue evaluations to predict material resilience and failure points under cyclic loading. These findings support the development of effective maintenance and reinforcement strategies, contributing to enhanced track longevity and safety. Full Text
